Question 15 Which of the following statements about passive transport is true? (5 pts) Your answer: The input of ATP is required in order to facilitate transportation. Substances move from areas of high concentration to areas of low concentration. Passive transport refers only to the movement of water molecules. Membrane proteins are always needed in order for it to take place.

Which of the following statements regarding passive transport is false? All passive transport relies on a concentration gradient as the driving force Facilitated diffusion can move solutions against their concentration gradient Osmosis involves the movement of water to equalize concentrations Ions require special protein transporters to diffuse in and out of the cell
